I have a 2TB disk that used to be visible. Now it is not. I think my data is there.
When I started after ANALYZE I got the following ...
D Linux and numbers followed
D Linux Raid and numbers followed

Then I fiddled with Testdisk and now I get, after selecting ANALYZE.....
(I think I tried to change the partition format hoping it would help)

Invalid NTSF or EXPAT boot
1 * HPSF - NTSF 0 0 2 243152 20360 3906249728
1 * HPSF - NTSF 0 0 2 243152 20360 3906249728

Can this be fixed?
What should I do now?
Thanks

Your message means either your bootsector is damaged or your partition table doesn't fit?
Please run Analyse, Quick Search and if no partition is found, Deeper Search also.
You'll find a testdisk.log within your testdisk folder.
Please open it using a wordprocessor like wordpad and copy and paste the content of your testdisk.log into your next post.

I did as requested, and here is the log.
At the end of ANALYZE the screen showed the following but this is not in the log file.


D Linux 0 0 2 243152 203 60 3906249728
D Linux Raid 0 0 2 243152 208 1 3906249984

Status: Bad

Sectors are not identical.

A valid NTFS Boot sector must be present in order to access
any data; even if the partition is not bootable.

I am still hoping that someone would give me some advice here. I hesitate to go making changes by myself for fear I will accidentally erase my data.
